Vehicle Interior Surface Textile With Slip-Resisting Rear Side
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interior components with adhesively bonded textiles in vehicles have a shorter lifespan and limited recyclability due to the difficulty in replacing the surface material, which restricts the reuse of materials at the end of the vehicle's life cycle.
Innovation Solution
A surface textile with a slip-resisting rear side, differing from the front side in structure and composition, allows for adhesive-free coupling to a carrier, enhancing adhesion and preventing displacement, thereby enabling reuse and maintaining visual appeal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If adhesive is used to bond the surface textile to the carrier, then the textile is securely fixed and cannot be displaced, but the textile becomes difficult to replace and materials cannot be reused at the end of the vehicle's life cycle
Solution Approach 1:
The patent replaces the chemical bonding system (adhesive) with a mechanical interlocking system. The carrier features a three-dimensional structure with protrusions and recesses that mechanically engage with corresponding features in the textile, providing secure fixation without adhesives. This mechanical system allows the textile to be firmly attached during use while enabling removal and replacement at the end of the service life, thus resolving the contradiction between fixation stability and reusability.
2Reliability
If adhesive is used to bond the surface textile to the carrier, then the textile remains fixed during vehicle operation, but the interior components have a shorter life cycle and limited recyclability
Solution Approach 1:
The patent replaces adhesive bonding with a mechanical interlocking system featuring protrusions and recesses that provide stable attachment during vehicle operation. The mechanical engagement ensures the textile remains firmly fixed under normal operating conditions while allowing for clean removal without damage to either the textile or carrier, thereby extending the reusable life cycle of the interior components and improving recyclability.
3Reliability
If the rear side of the textile has a slip-resisting property for adhesive-free coupling, then the textile cannot be displaced relative to the carrier, but the textile structure becomes more complex with different front and rear sides
Solution Approach 1:
The patent applies the local quality principle by differentiating the properties of the textile's front and rear sides. The rear side is specifically designed with a loop pile structure and increased surface area to provide slip-resisting properties for mechanical interlocking with the carrier, while the front side maintains a smooth, aesthetic appearance suitable for the vehicle interior. This localized differentiation achieves displacement resistance without requiring the entire textile structure to be complex.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The surface textile effectively adheres to the carrier without adhesives, reducing displacement and extending the lifespan of interior components while facilitating recyclability and maintaining aesthetic and haptic properties.
Implementation Method 1
The rear side has in this case at least a slip-resisting property

AI summary
A surface textile for an interior component of a motor vehicle has a front side and a rear side. The rear side is able to be coupled to a carrier for forming the interior component of the motor vehicle. The rear side has at least a slip-resisting property. The front side and the rear side differ from one another in terms of their textile structure and/or in terms of their textile composition.
